How boring was that? And did you see how much real estate those organic results took up, including unpaid shopping results? That’s no way to run a profitable search engine.

I hope the sarcasm here is obvious, especially for my dear SEO friends that have an increasingly hard time showing up above the fold.

As you’ve noticed, things have changed and now the SERP for the same search looks like this:

To use Google’s own words, they have been “Giving customers more reasons to click your ad”.
Most of these reasons come in the form of Ad Extensions. I’ll leave the prominent Shopping results for a later post in this series.

Ad Extensions come (and go) in a fast pace. Since 2010, Google has been releasing one extension after the other and there always seems to be at least one extension in beta at any given time.

How different each of these extensions may be, they all have one thing in common: they increase the CTR of your ads. How much depends on the extension, but it’s usually in the 5-30% range.

As I do not know an advertiser that isn’t interested in a higher CTR (for the same position & CPC), the advice here is simple: use any extension that makes sense for your business. And besides, Google wants you to use extensions so badly, they explicitly made it part of Ad Rank recently.

The best practice however, hasn’t changed due to this Ad Rank update: if you aren’t already using all extensions that are relevant for your business, you definitely should by now.

To help you get a quick feel for the current Ad Extensions, when to use them and what to expect of them, I’ve created the features comparison chart below.

You won’t find product or offer extensions, since these have been quietly retired. You also won’t find image extensions as only a very small minority of advertisers seems to be eligible to use these. Neither will you find Dynamic Search Ads, even though it can be found in the Ad extensions tab in AdWords, I consider it more of a campaign type that will be covered in the Testing part of this series.

However, you’ll find 8 other extensions (of which 1 is currently in beta) that will provide you with more than enough possibilities to stand out and increase your CTR.

The CTR improvement numbers above are the numbers that were published by Google when releasing that specific extension, based on their initial (but significant) findings with beta users.

The actual numbers will vary by country, industry, advertiser and it will especially be dependent on how many competitors are already using a specific extension. For example, if you’re the only advertiser with seller ratings for a specific search query, chances are this will greatly benefit your CTR.

On the other hand, if you’re the only one without seller ratings, you’ll still stand out, but probably not in a way that increases CTR.

As I mentioned in the introduction part of this series, implementing Ad Extensions can be considered a quick win. That’s why it’s pretty high up in the order of priorities in this audit series: it doesn’t take a lot of time to add, but the benefits will come immediately after adding the extensions.

Make sure each of your search campaigns has at least 4 sitelinks.
You can always add more if you want to, especially if you want to compare how the ad performs when different sitelinks appear (just make sure the position stays the same for a fair comparison).

Add descriptions to the sitelinks of your branded campaigns or add at least 6 sitelinks without descriptions to your branded campaigns.You could add additional descriptions to all of your sitelinks, but so far they seem to appear only on branded queries. So if you want 4 sitelinks with descriptions on your branded queries, add descriptions to those sitelinks.
However, if you’d rather have 6 sitelinks without descriptions instead, well then add 6 sitelinks without descriptions.
Either way, there’s no need to spend a lot of time adding sitelink descriptions in non-branded campaigns.

Create ad group level sitelinks for ambiguous and/or high volume ad groups.All paid search practitioners rejoiced when it became possible to add sitelinks on the ad group level with enhanced campaigns. However, it would be pretty time consuming to create a unique set of sitelinks for each of your ad groups.
So the best course of action is to create ad group level sitelinks when the campaign level sitelinks aren’t optimal, given the keywords in the ad group. Especially in ad groups with:

Many impressions in the top positions.

Ambiguous queries, so you can narrow down the user’s intent. Read all about those (including an interesting case study) in Should You Create Ad Group Sitelinks in Enhanced Campaigns? by Brad Geddes. The good news is that by now, AdWords Editor fully supports ad group sitelinks (version 10.2 and higher).

Don’t worry too much about individual sitelink performance

Whenever you analyze the data in the Sitelinks Extensions view under the Ad extensions tab, you should realize that you’re looking at the performance of the whole ad unit whenever that particular sitelink appeared, not at the individual sitelink performance.

If you want to be shocked and see that, click the Segment drop-down menu and select ‘This Extension vs. Other’. You’ll see that very few users actually click on the individual sitelinks. What I usually see is a CTR of less than 0.10% per sitelink for non-branded campaigns and 1-2% for branded campaigns, but you should check your own numbers to be sure. Sam Owen at PPC Hero had similar findings in his Case Study: Do People Actually Click Sitelinks?

However, sitelinks significantly increase the CTR of the ad as a whole. So that’s how you should treat them: additional description lines that take up real estate and give you an opportunity to show additional options, features, benefits and USP’s. Even if most of the searchers won’t click on the sitelinks themselves, they will see them and they will impact the performance of the ad as a whole.

So the question is not so much: how many people click on this particular sitelink and what happens after that? But more: which combination of sitelinks generates the best performance for my ad as a whole?

Call Extensions

If you value calls to your business, you should definitely add call extensions to your campaigns, especially if you’re also advertising on mobile devices and have a local business. As Google research shows “70% of mobile searchers use click to call”.

And in case you’ve missed it, since April 2013, you’re no longer allowed to use phone numbers in the ad text, so the only way to show your phone number is by using call extensions.
The call extensions support page will show you how to set them up and monitor their performance.

Just a couple of best practices to keep in mind:

Consider a Google forwarding phone number, currently only available in the U.S., U.K., France and Germany. This way you can track phone calls as conversions when they last longer than a number of seconds of your choosing.

The question remains if you’ll value such a ‘conversion’ just as much as any other conversion you’re tracking in your account. If you’re an e-commerce advertiser, that’s probably not the case. On the other hand, if you’re a lead-gen advertiser or a local business, phone calls may be your primary conversion. So, as is often case, it depends on your business goals whether you should choose a forwarding number or your own phone number.

If phone calls are really important to your business, you should also consider a call tracking solution that tracks calls to phone numbers on your website, as mentioned in the Measurement part of this series.

Schedule your call extensions, so you only show the phone number (or call button) when there’s someone there to answer the phone.

Location Extensions

If you have (a) brick and mortar business location(s) you’d like (mobile) searchers to visit, you should add Location Extensions. Just like call extensions, location extensions are especially effective for local businesses.
The easiest way to do this, is to link your Google Places and AdWords. The exact set up depends on whether you’re using upgraded or legacy location extensions, you can see how both work on the location extensions support page. And of course, make sure you comply with the with the location extensions policy. Once you’ve added location extensions to all relevant campaigns, there’s not much to it except monitoring the performance.

Though, there’s an extra option you may want to consider, especially for mobile searchers: apply a bid adjustment when people are searching within a specified radius around your current location extensions. Here’s how to do that:

Go to the Settings tab of the campaign you want to use such a bid adjustment.

Click ‘Edit’ next to Locations

Click ‘Advanced search’.

Click on the Location groups tab.

Select ‘Location extensions’ in the drop-down menu as location group type:

Specify the radius around each location extension.

Click the Add and Done buttons.

Now this radius has become a location for which you can apply a bid adjustment, under the Locations tab of your campaign settings:

Seller Ratings

Although you won’t find seller ratings as extension under the Ad extensions tab in the interface, it’s one of the most powerful extensions out there.

To get these coveted stars in your ad, you’ll need to meet a couple of requirements:

Your business must have at least 30 unique reviews in the past 12 months and an average rating of at least 3.5 stars. These reviews should reflect customers’ overall experience with your business, not so much with particular products you sell.

At least 10 of these reviews must be in the customer’s Google interface language. Seller ratings currently show on Google.com, Google.co.uk, Google.de, Google.fr and Google.nl.

Once you meet these criteria, seller ratings will automatically show up in your ads. Obviously, the more reviews you have (compared to other advertisers on the same SERP), the more effect this extension will have.

So if you want those stars in your ads, the best thing to do would be to open an account with one of the mentioned review websites and solicit reviews (through e-mail) from your customers after they’ve received your product / done business with you. I’d recommend reading How Ratings Extensions Gave a Boost to CTR for Shop Bedding for an interesting case study on how to do this.

If you have a positive third-party review, award or ranking in English and are able to fit the quote and the source in a total of 67 characters (and of course, meet all requirements in the review extensions policy), then you could add this as a review extension. Individual customer reviews won’t be accepted, that’s what seller ratings are for.

Especially if you’re in an industry people are skeptical about (think: weight loss, quit smoking, hair loss treatments, etc.), this extension could boost your credibility and definitely be worth the trouble. But so far, Google seems pretty strict in which sites they accept reviews from.

This extension is currently in beta, so no official support page here. However, you can read the following article where it was spotted: Google Testing New AdWords Site Search Extension.
We’ve been using it for a couple of clients and seen positive results, especially on branded and generic terms for e-commerce advertisers.

This is how the Form Extension works:

It allows you to place a field and button in your search ads, in order to direct users to a landing page based on a URL parameter.

You choose the text in the field, on the button and the URL parameter you want to use.

When users fill in a keyword (or zip code) in the field and click the search button in your ad, what they’ve filled in will populate the parameter to create the landing page.

If you’re interested in this extension, ask your Google rep for more information.

I’m sure this post will need an update soon, so keep your eyes open for any new extensions that will be released.

Hi Nils, you’re right, form extensions are no longer available since October 2014. Not all betas make it 😉

Previous visits is an automated extension, so no way to know what the exact impact is of those. I assume it’s in the lower range as it’s a quite subtle extension.

Concerning dynamic sitelinks, I think it’s best to add sitelinks yourself to all your (important) search campaigns. But even then, Google says “If you’ve already set up your own sitelinks, those will always show, except for the few instances when the dynamic sitelink can perform better.” You could opt out of dynamic sitelinks if you see them showing up instead of your own sitelinks and you’d rather use your own sitelinks. See: https://support.google.com/adwords/answer/6058574

In general my advice for all extensions would be: add all the ones that make sense to you and Google will end up showing the combination with the highest CTR, which is both in your as well as in their best interest.
